Description
Dual electro-optic frequency comb THz system: phase-coherent chirped pulses drive electro-optic modulators to generate flat THz combs in a photoconductive switch, down-converted to RF below 1 MHz for sensitive, fast (bio)molecular sensing; demonstrated on formic acid, with 1570 nm waveguide photomixers and a 4–350 K cryostation being added.
